IMPROVEMENT IN SPRINGS.-

The Schcdulo referred. to in these Letters Patent and making part of the same To on whom it may concern Beit known that I, J OHANN M. SCHMIDT, ofNew Albany, in the county of Floyd, and in the State of Indiana, have inveutedcertain new and useful Improvements in Springs; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a spring forloconlotives, railroad-cars, 850., as will be hereinafiaer fully set forth.

In order to enable'others skilled in the artlto which my invention appertains, to make and use the same, I will nowproceed to describe its construction and operation, referring to the annexed drawings, in which-- Figure 1 is a side view of a car-spring;

countersink from the'uuder side, which projects into a slot in the leaf above, thus l'iOldlllgJthl-EIGHNQSll] position, and at the same time allowing them to slide or give, as occasion requires.
